MACHINE FOR TRUING LOCOMG'I'IVE DRIVING-WHEELS.

To all whom it may-concern:

' Be it known that we, Josnrn C. TYLER, JOHN A. BEHRENDS, and LAKE PARKS, citizens of the United-States, residing at Abilene, in the county of Taylor and State of Texas, have invented certain new and useful Improvements in Machines for Truing Loa a machine of this character which is adapted to be appliedtothe track rails and operated upon each wheelseparately after the same has been jacked up sufficiently to clear the track, thus obviating the necessity of removing the wheels from the locomotive.

It is the general practice at the present time, when wheels become flat or worn so as to be irregular, to remove the wheels from the engine and put them in a lathe for the purpose of truing the tread and flange; It

" is obvious that such methods are expensive.

In our device, an engine may be run into a round house or repair shop where power may be obtained, the device clamped to the rail and the wheel jacked up to clear the track, the power is then applied and the wheel is turned and trued at one operation.

Another object of the invention is to provide a machine of this'character which will possess advantages in points of efficiency and durability, is inexpensive of manufacture and at the same time is simple in construction and operation.

With the above and other objects in view, theinvention consists in the novel features of construction and the combination and arrangement of parts hereinafter more fully.

Specification of Letters Patent. Application filed March 15, 1913. Serial No, 754,648.

'tives; Fig. 2 is a to lan vi -IFi .8 is'a vertical sectional vihv ii; Fi l l isf transverse sectional view; and l ig. 5 is a longitudmal. sectional view illustrating the apphizatio n of our machine to the top of a ran Referrin more articularly to the drawmgs, 1 m 'cates t e body member of the machine which is constructed of steel or other suitable metal and bifurcated at its lower end as shown at 2 to form two oppositely disposed members .3 which are adapted to be arrangedupon opposite sides of the tread of the rail and rigidly secured thereto by means of the vtapering wedge members 4,. The wedge members are driven Patented Feb. 3, 1914.

in between the tread of the rail and the inner walls of the members 3, each of said wedge members beln driven in from opposite directions, so t at they will securely clamp the body member to the rail, it being apparent that the main portion of the body 1 will rest upon the upper face of the tread. The body member 1 is provided with the transverse opening 5 in whichismounted a power shaft 6, having the worm gears 7 and 8 mounted thereon and disposed upon opposite sides of the body. It will be understood that the shaft 6 may be driven by any suitable form of motor (not shown).

Secured to each side of the body member 1 and arranged adjacent the front and rear sides thereof are the bearings 9 in which are mounted the shafts 10 which are adapted to be disposed at an angle with respect to the body as clearly shown in Fig. 1. Mounted upon the outer ends of the shafts 10 are the corrugated rollers 11 which are adapted to engage upon the opposite sides of the flange of the wheel to rotate said wheel when motion is imparted to the gated plate 14. The ends of the bearing.

plate 13 are provided with the enlarged portions having the arcuate undercut side walls 16 formed in the inner faces thereof, said undercut side walls being adapted to receive the tapering arcuate ends of the plate 14. Formed upon the upper face of the plate .14 is an elongated enlarged portion 17 which is provided with a centrally'arrangedgroove 18 closed at oneend as shown at 19. Slidably mounted upon the enlarged-portion 17 is an, adjustable block17' having undercut side Walls 18' adapted .to receive the tapering side edges of the enlarged portion 17. Formed integral with the under side of the block 17 1s an apertured lug 19 which is disposed within the groove 18. A longitudinal screw 20 is mounted in a suitable, bearing 21 which is arranged within the closed end 19, the inner end of said screw being mounted in the apertured lug 19' whereby the block 17 may be laterally adjusted with respect to the periphery ofv the locomotive wheel.

Secured to the outer end of the screw 20 is a handle member 22 whereby the screw may be readily manipulated to adjust the block 17 t The elongated plate 14 is provided at one end and 'u on the under'surface thereof with the serratlons 19 which are adapted to be engaged by the worm car 20 mounted upon the transverse sha 21 whereby the plate 14 may be readily rotated. A sultable handle member 22 is mounted upon the outer end of the shaft 21 by means of which the shaft may be readily rotated to adjust the plate 14'. I

The tool standard 23 is carried by the 1 central portion of the block 17 and adjustably mounted therein is a shank 24, said shank being held in various adjusted positions by means of the set screw 25 carried by .the standard 23. Adjustably secured within the outer end of'the' shank 24 is a cutting knife 26, which is held in various adjusted positions by means of the set screw 27. Thus as the wheel is turned by means of the cor.-

' rugated rollers 11, the cutting knife 26 can be readily adjusted to various positions so that the uneven surface of the tread of the wheel may be readily evened off.

Secured to one end of the bearing plate 13- and extending upwardly from the body in a substantially vertical position is a brace member 28, the upper end of which is securely bolted by means of the bolts 29 to one of the longitudinal arms of the bracing frame 30. Securely bolted to the frame 30 is a supporting plate 31.

The numeral 32 indicates the trunnion of' the trunnion by means of the babbitt 35,

which 'forms a suitable bearing for the trunnion 32. Arranged between the plate 31 and v adapted to mesh with the worm gear 40 mounted upon one of the shafts 10. Mounted upon the upper end of a shaft 37 is a worm gear 41, said Worm gear meshing with a suitable gear 42 mounted upon the outer end of the screw 20. When the block 17 is in a position wherein the apertured lug 19' is at the outer end of the screw 20, the worm gear 41 is engaged with the gear 42 by means of the bell crank lever 43 which is mounted upon the end of the bearing plate 13. From the above, it will be seen that the block 17 may be readily and quickly adjusted by engaging the worm gear 41 with the gear 42.

From the above description taken in connection with the accompanying drawings, it will be readily apparent that we have provided an improved machine for turning and truing locomotive drive wheels at one operation.

In the practical use of our invention, the

locomotive wheelis first jacked up clear of the track and the body member 1 is then securely clamped to the tread of the wheel beneath one side of the wheel, power is then It will be readily apparent that in using our improved machine, the body 1 is securely clamped to one of the rails beneath one of the driving wheels of the locomotive. After the uneven surface of the tread of this wheel has been removed, the body is released from the track and placed beneath the wheel upon the opposite side of the locomotive and readily secured to the track rail to hold the same against movement, while removing the uneven surface of the second wheel. It will also be apparent ,that the device is extremely simple in construction and at the same time can be manufactured at a comparatively low cost.

While we have shown and described the preferredform of our invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying our in- 'vention into practice, without sacrificing any of the novel features or departing from the scope of the appended claim.

What we claim is In a device of the character described, the combination of a body member, means for securing said body in a rigid position, a driving shaft mounted in said body, angular shafts disposed upon opposite sides of the body, means for connecting said shafts with the power shaft, corrugated rollers mounted upon the upper ends of the angularly disposed shafts and adapted to engage opposite sides of a wheel to rotate the same, and a cutting tool ad'ustably mounted upon said body and adapte to engage the perlphery of the wheel.

In testimony whereof we hereunto affix our signatures in the presence of two witnesses.
